TECHNICAL FIELD

This invention is in the technical field of bag for digital devices, especially with self-lock high-pressure sealing device.

BACKGROUND TECHNOLOGY

Storage bags are widely used in various applications. With the continuous updates of digital devices, storage bags for these devices also updates, e.g. mobile pouch and computer sleeve. However, most storage bags available in the market don't have the waterproof function, making it impossible to use the digital devices in the water. For example, when people are having fun by the seaside, in the sea or swimming pool, they can't always feel free to use such digital devices (including mobile phones). Should the digital devices drop into water, these devices will fail to use or lose important data which can lead to serious consequences. Beside, the storage bags available in the market have bad strength resistant ability and are easy to be broken in high pressure environment which may cause the digital devices into water.

ABOUT THE INVENTION

This invention solves the technical issue by providing a bag for digital devices with self-lock high-pressure sealing device with good high-pressure water-proof performance.

This invention provides a technical solution via a bag for digital devices with self-lock high-pressure sealing device, including the lock body and lock core. The lock body has a long cylinder with a groove at one side. The width of the groove is smaller than that of the lock core. At the inner side of both sides of the groove, there is a slope. The lock core is located in the long cylinder. The lock core and lock body are fixed by a positioning mechanism making the two interact with a proper clearance which is smaller than the thickness of the bag for digital devices.

The positioning mechanism includes the core locating hole at one end (outside) of the lock body and the dowel pin at the end of lock core. The locating hole and dowel pin interact with each other to make the lock core suspend in the cylinder.

The inner wall at the lock body ends has a spherical surface; the end of the lock core where no dowel pin is set has a curve structure. At the end of this curve structure, there is a round ball.

The above-mentioned curve structure has a gradient of 30°.

The slope at the inner side of both sides of the groove is angled at 30°.

The lock core is of triangular structure being composed of three strings of different thickness, height and angles.

At the end of lock core where the dowel pin is made, there is a spacing sheet.

A hanging loop is made at the lock body.

A baffle is set in the tangential direction along the side of the cylinder. The groove is below the baffle.

The bag for digital devices has a plastic seal at the opening.

Advantages of the Invention

Compared with the current technologies, the above-mentioned technical solution in this invention has the following advantages and positive effects. The interaction between the lock body and lock core makes the clearance in-between less than the thickness of the bag, making the bags sealed in the cylinder of the lock body. The spherical surface is made inside the lock body and along its opening, while the end of the lock core is angles at 30° with a ball attached and fit with the spherical surface. All these make the bag (after being folded) more easy to come into the lock body. A hanging loop is made at the lock body for convenient carry-on and no easy missing.

IMPLEMENTATION OF THE INVENTION

The invention will be further described in details via the examples set below. It should be understood that the examples are only used to describe the invention but not to restrict the applications of the invention. It should be further understood that the technicians in this field can make any alternations or modifications after reading the contents herein. Such alternations or modifications shall be deemed as equivalent to the examples and shall be limited within the scope of the Claims attached to this invention application.

The implementation of this invention is related to a bag for digital devices with self-lock high-pressure sealing device, as shown in the FIG. 1, FIG. 2 and FIG. 3. This bag includes the lock body (1) and lock core (2). The lock body (1) has a long cylinder (11) with a groove (12) at one side. A baffle (17) is set in the tangential direction of the body (1) along the cylinder (11). The groove (12) is below the baffle (17). The width of the groove (12) is smaller than that of the lock core (2). At the inner side of both sides of the groove (12), there is a slope which is angled at 30°. The lock core (2) is located in the cylinder (11). The lock core (2) and lock body (1) are fixed by a positioning mechanism. This positioning mechanism includes the core locating hole (14) at one end (outside) of the lock body (1) and the dowel pin (21) at the end of lock core (2). The locating hole (14) and dowel pin (21) interact with each other to make the lock core (2) suspend in the cylinder (11). The inner wall at one end of the lock body (1) has a spherical surface (15). The end of the lock core (2) where no dowel pin (21) is set has a curve structure angled at 30°. At the end of this curve structure, there is a round ball (22) which can be made into the folded bag (3). The lock core (2) is of triangular structure being composed of three strings of different thickness, height and angles. At the end of lock core (21) where the dowel pin (21) is made, there is a spacing sheet (23) limiting the position of the lock core (2), preventing from slip and limiting the position of the bag (3). A hanging loop (16) is made at the lock body (1) for each carry-on and no easy missing.

The polymer PC resin by DuPont can be used to make the lock body in this invention after being modified and the injection molding process. The internal wall of the lock body is a long cylinder with a long groove at one side. At the both sides of the groove, there is a slope angled at 30°. In the cylinder, a PE lock core is placed. A lock core locating hole is made at one end of the lock body to fix the core. At the other end of the body, a spherical surface is made at the edge of the inner wall. The end of the lock core is curved at 30° exposed out of the lock body and with a round ball attached. The lock core is between the lock body and inner wall with clearance left. The lock core is of triangular structure being composed of three strings of different thickness, height and angles. With the fixture via the locating hole at one end of the lock body, the core suspends in the cylinder.

The bag has a plastic sealing strip and is clipped between the lock body and lock core. After the bag is folded along the strip, the core is inserted into the fold. Then the bag and the core together are inserted into the lock body from the core end where there is a round ball, leaving the bag body out. With a mobile phone in the bag body, at this time, there will be one atmosphere pressure around the phone. When the air pressure in the bag equals to the outer air pressure, the bag is sealed. When the outer air pressure increases, the bag body will be expanded along which the lock core will also be expanded. The triangular strings of the lock core being pulled will then lock the groove. The greater the pressure difference, the greater the locking force. This bag can withstand 100 KG pressure with high-pressure sealing function. With enough air in the bag containing a mobile phone, when it's put on a smooth floor and stepped, the phone will be safe and ground and the bag will not be broken. When diving into as deep as 30 m, the mobile phone can still be used if it's put in this bag. The bag will not be broken due to the high pressure around and no water will get in.

It's not difficult to find that the interaction between the lock body and lock core makes the bags sealed in the cylinder of the lock body. The spherical surface is made inside the lock body and along its opening, while the end of the lock core is angles at 30° with a ball attached and fit with the spherical surface. All these make the bag (after being folded) more easy to come into the lock body. A hanging loop is made at the lock body for convenient carry-on and no easy missing.
